Hi all,
I've slowly been learning and getting the hang of things. Stuff is becoming more and more predictable which is nice.
However, I've noticed something and I wanted some input on it.
When milling 1/8" thick sheets of hot rolled steel it seemed like it milled fantastic in one direction, and poorly in the other.
Also, I milled a bunch of 1/2" thick 304 SS plates recently and in one direction they did great with conventional milling, and when I turned them 90 degrees I ended up with a horrible finish until I switched to climb milling which left a gorgeous finish.
It seems like this stuff has a grain, similar to wood.
Is this the case? Am I imagining it?
The 304 stainless really surprised me, and even more so when switching to climb milling left such a beautiful finish. Conventional milling left a terrible finish, rougher than cast iron while climb milling was smooth as can be. I've been climb milling more and more, but I would like to understand what's going on.
In the 304 situation I was using a 1/2" AlTiN coated carbide endmill with a mister, 1400 RPM, 7 IPS with 0.5" depth of cut and 0.125" radial cut.
